Denmark in 5 days

Hi,

Was thinking about taking a short vacation to Denmark for around 5 days.

The dates will be around 14.10 - 20.10.

Wanted to know if now the weather is comfortable for a trip, and second what are the most beautiful places to see in Denmark. I'm looking to see mostly nature, I'm less interested in museums or sitting on the beach. We're young so even a cool young neighborhoods are cool to explore and I always appreciate seeing some local stuff. (maybe some danish folk music show, vikings stuff, danish food etc..)

I read a bit about Møns Klint, Råbjerg Mile, Rubjerg Knude lighthouse, Aarhus, Odense and Bornholm, but would appreciate other tips and recommendation for other places.

So I would appreciate some help choosing places and planning my itinerary assuming landing in Copenhagen and having full 5 days. (I can have an extra day if needed, and let's assume one day just walking around Copenhagen).
